Low temperature technology

The varied applications of our low temperature systems range from test stand technology through the pharmaceutical and medical industries to food production.

Through the use of special components, two-stage compressor technology and special low-temperature refrigerants, we easily achieve supply temperatures of down to -50°C. Brine/glycol, thermal oils or air are used as coolants.

Taking your requirements into account, we develop an efficient and reliable low temperature concept. By means of project-specific control system, we always guarantee high control accuracy – even the connection to superordinate automation systems and the integration of on-site control equipment are no problem for us.

If required, we can also integrate the necessary hydraulic accessories such as pumps, control valves or buffers and consider your factory specifications.
